How to force Microsoft Edge to use the best GPU on Windows 10

You can now set the default GPU that Microsoft Edge uses to improve performance, and in this guide, we'll show how to do it on Windows 10 April 2018 Update.
Modern browsers often offload graphic-intensive tasks to the GPU to improve your web browsing experience, freeing up CPU resources for other tasks. If your system has multiple GPUs, Windows 10 can automatically decide on the optimal one for Microsoft Edge to use automatically — but that doesn't necessarily mean the most powerful one. Now with the April 2018 Update (version 1803), you can manually select the default GPU that Edge uses to improve its performance.
The new Graphics settings page available in the Settings app that allows you to manage the graphics performance preference per application.GPU manufacturers like Nvidia and AMD have their own control panel apps with similar options, but now you can do it directly from the Windows 10 settings.
